Circuit is 6sn7 voltage gain, the el84 cathode follower direct to 211 grid, in a similar fashion to Ongaku. The A2 driver is capable of sending the grid at least 40v positive, so peak power is just above 30w. All transformers by Sowter Transformers 211 DC heated...

Valve phono stage using a JFET/ECC88 cascode to provide the gain and low noise of a solid state stage without the sonic cost of silicon and all the overload and sound advantages of valve stages. SPECIFICATIONS Overall gain 62dB at 1kHz Overload at 42v RMS output (40mv...

Transformer coupled (Sowter), front and back, balanced gain stage, valve rectified, choke regulated power supply. This design was started when I was asked for the “Best preamp you can make” So this is it. There are some test results available, but the...
